IMPROVEMENT I SULKV-PLOWS.

Specification forming part of Letters Patent No. 167,159, dated August31, 1875; application filed December 21, 1874.

To all lwhom 'it may concern: Y

Be it known that I, ROBERT R. FENNER, of.' Urbana, county of Champaignand State of Illinois, have invented certain Improvements inSulky-Plows.

The following description, taken in connectionwith the accompanyingplate ,of drawir gs hereinafter referred to, forms a full and exactspecification, wherein are set forth the lrature and principles of theinvention, by which the same may be distinguished from others of asimilar class, together withsuch parts thereoi` as are claimed as newand are desired to be secured by Letters Patent of the United States.

My invention relates to that class of plows commonly known assulky-plows 5 and the nature thereof consists in certain improvements inthe details of the construction ofv the same and novel combination ofparts hereinafter shown and described.

In the accompanying plate of drawings, in which corresponding parts aredesignated by similar letters, Figure l is`a lateral longitudinalelevation of the machine. Fig. 2 is a plan ofthe same. Figs. 3 and 4illustrate, in. detail, detached parts.

A designates the beam, the forward end of which is pivoted between thetimbers E E, which timbers may be adjusted at any desirable point uponthe axle G by means of the screw-bolts e and metallic bars e. The saidbeam is raised or lowered by means of the lever D, which is providedwith fulcrum-irons d d1 on the upper and, lower sides thereof. The lowerfulerum-iron d may be hooked upon the lower bolt A', passing through thefulcram-post T, and the upper fulcrum-iron ell may be hooked upon theupper bolt e', passing through the said fulcrum-post. The upper bolt is,of course, made use of when it is desired to raise the beam to itsgreatest eleva tion. Upon the rear end of the said lever is an eye, d2,through which passes the rod a, which is secured upon the said beam atan augle therewith.

When the operator desires to raise the plow he presses with his footupon the said lever, and when he desires to force the plow downward heraises the lever with his hand. The timbers E prevent the said beam frombeing moved to the right or left and steady it in position.

When the operator desires the plow to run a little deeper for a shortdistance, he merely raises the forward end of the lever, and when hewishes to lower the plow from its raised position he simply disengagesthe said lever from the said fulcrum-post, and by it lowers the plow tothe ground.

- The depth of the furrow may be accurately regulated by raising thewheels and securing them in any desired position by means of the angulariron pieces F, which are rigidly attached to the extremities of theaxle-beam G. rIhe said angleirons are provided with vertical oblongapertures, through which pass the spindles L, upon which the wheelsrevolve. Upon the sides of the said vertical apertures are arranged aseries of teeth for the reception of corresponding teeth formed on thewashers N upon the rod l of the spindle. The said rods are flattened sothat they will not turn in the said apertures, and are firmly secured tothe said anglebar by causing' the teeth of the washers to engage withthe teeth on the angle-bar, and then clamping the said washer firmly inposition by means of the nut M.

When it is desired to cause the plow to take more land, the beam may bemade to form a slight angle with the bar G by means of the bolt e andmetallic bars e.

The plow-beam may be held in position, when either raised or lowered, bymeans of the lever o, which is pivoted to one of the timbers E. When thesaid beam is raised the short arm of the said lever is placed beneath it5 when lowered, above it.

P designates the draft-bar, secured in position by bolts and by thebrace g, to which the double-tree may be attached.

The point of the plow can be raised or lowered by means of thescrew-bolt Y and the bar U, provided with an oblong aperture, o, throughwhich the said bolt Y passes.

Having thus described the construction of my invention, I will indicatein the following clauses what I claim and desire to secure by LettersPatent of the United States-that is to say:

l. The lever D, provided with fulcrum-irons d d1, in combination withthe fulcrum-post.

2. The combination of the following elever D, crossbar g, and tongue P,as shown ments: the beam A, pivoted between the tim and described. bersE E, which may be adjusted to any delu testimony that I claim theforegoing I sirable point upon the axle G, the lever D, `hztve hereuntoset my hand. provided with fulorum-ironsd d1, and the ful- ROBERT RFENNEB Crum-post T.

3. The combination of the following ele- Witnesses: ments: the lever o,pivoted to one of the M. LINDLEY, timbers E, timbers E E, plow-beam A,le- J. A. MYERS.
